Wow, I'm a little overwhelmed, but please keep the info coming! Its going to take some time for me to digest.I was looking for a computerized one primarily for one reason - this will be a bonding adventure for me and my 8 year old son. I don't know if he'll have the patience to watch me operate it manually.I found this on craigslist, an orion astroview 6 eq with lots of accessories for $375http://southjersey.craigslist.org/pho/4572584716.html
OK, I've done some more research, but not everything yet. I looked at the Orion 8" dobsonian, it looks very nice, but is really too large and heavy. Even the smaller 6" is too large. Nearly 4ft tall and 40lbs!I am hesitant about joining a club or attending any events right now, but would be a lot of fun later on.I contacted Orion/telescope.com and they recommend a Star blast 90 AZ refractor with barlow and kit (kit would be good for my son). The also suggested a skyglow filter to help with light pollution. I don't know about the scope - it doesn't look too substantial.http://www.telescope.com/Telescopes/Refractor-Telescopes/Refractor-Telescopes-for-Beginners/Orion-StarBlast-90mm-AZ-Telescope-amp-Beginner-Barlow-Kit/pc/1/c/10/sc/331/p/106874.uts
This is your average inexpensive telescope, nothing great, flimsy feel and look. But if you want light weight , portability, and cost within your requirements. This fits the bill. But It will not be the easiest to use for a child, the design of the inexpensive mount will make the view very shaky in all but the most delicate touch hands. This scope will also suffer from chromatic aberration ( purple color fringe around the moon). And at 90mm aperture, everything but the moon and planets will appear very dim.May I suggest this Orion 6" dob http://www.telescope.com/Telescopes/Reflector-Telescopes/Reflector-Telescopes-with-Altazimuth-Mounts/Orion-StarBlast-6-Astro-Reflector-Telescope/pc/1/c/11/sc/342/p/102011.uts?refineByCategoryId=342It has much better light gathering than a 90mm refractor,so images will be brighter and more satisfying. It uses a mirror to magnify light so it does not suffer from this chromatic issue. The mount is short and sturdy with the ability to dial in the correct amount of drag for anxious and indelicate little hands.It is small and light 23 lbs and most importantly its design will allow your young son to operate it easily and intuitively.Its designed for use on a table top, but setting it on stool, milk crate or cinder block will make 360 degree viewing much easier. Viewing under light polluted skies is unsatisfying with any scope, That skyglow filter will not really help...so try to make trip to darker skies when the moon is not up, you and your son will find its worth the trip.They also make the same scope with the digital push to feature so you can find things easier, for not too much more money.http://www.telescope.com/Orion-StarBlast-6i-IntelliScope-Reflector-Telescope/p/102026.uts
